Hi, I have 4 corys: 3 peppered and 1 panda. The panda cory has started spinnging and flipping around the tank so i figured it was a problem with his swim bladder so i added the swim bladder treatment on saturday. He seemed fine until just as he's started to flip around badly yet again. I'm not due to add the 2nd dose until wednesday so what else can i do until then? Add 2nd dose sooner? Could it be anything else because other than the swim bladder i have no idea what could be wrong. P.S my All water stats are fine. Thanks
